IRON PLANE.

Specification of Letters Patent.

Patented Mar. 3, 1914i.

Application filed April 9, 1913. Serial No. 760,062.

To all whom it may concern:

Be it known that I, THOMAS S. CARLISLE, a citizen of the United States, residing at Ocean City, in the county of Cape May and State of New Jersey, have invented certain new and useful Improvements in Iron Planes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to planes, and as its principal object contemplates the provision of a novel form of plane structure of such design and arrangement of parts that the planes may be made in various sizes, including smoothing, jack, and fore plane, which may be arranged within a single packing boX, the longitudinal dimension of which corresponds to the longitudinal dimension of the fore plane or larger of the set, and the depth of which corresponds to the depth of any one of the planes.

A further object of this invention resides in the provision of a novel form of plane toat which may be readily attached to or de tached from the body of a plane for the purpose of packing and storing the too-l within a tool chest or box.

A still further object of this invention aims to provide simple but effective means for locking the cutting iron of the plane in adjusted position.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claim which is appenc ed hereto and forms a part of this application.

l Vith reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice and throughout the several views of which similar reference numerals designate corresponding parts: Figure 1 is a top plan view. Fig. 2 is a section on the line 2-2 of Fig. Fig. 3 is a section on the line 3-3 of Fig. Fig. 4 is a section on the line H of Fig. Fig. is a detail view of the base portion of the detachable handle of this invention illustrating the several parts in disassembled relation; and Fig. 6 is a longitudinal sectional view illustrating a set of planes including a smoothing, a jack, and a fore plane, illustrated in the assembled position for packing and storing.

Proceeding now to the description of the drawings, this invention includes three main elements, the plane stock, the clamping dog employed in locking the iron in adjusted position, and the detachable toat. Taking up these features in the order named, the stock designated as an entirety by the numeral 1, in Fig. 1, includes the customary metallic shoe 2, carrying the integral side walls a which are enlarged as at 5 for the obvious purpose of protecting the adjusting mechanism for the iron. The shoe 2 is slotted in the usual manner, as at (3, and is also equipped with a bed block 7 formed with a diagonally extending bore 8 in which the worm adjuster 9 is journaled. an inclined faced abutment 10 is formed integrally with the upper face of the shoe 2, and inclines upwardly from the iron slot 6 to form a support for the iron 11, and to strengthen it at its cutting edge. The iron 11 is equipped with an adjusting block 12, attached to its under face by a bolt 1.3, or other suitable fastening means. This member 12 is threaded in the usual manner to permit the worm on the member 9 to effect the adjustment of the iron 11.

Taking up as next in order the description of the clamping dog employed in holding the iron 11, this feature of the invention includes a locking lever 14, enlarged at its upper terminal to produce a shoulder 1.5 which is grooved to form a channel adapted to partially encircle the pivotal rod 16 mounted at each terminal in a suitable aperture formed in the member The upper terminal of the member it carries a pivoted locking block 1'? from the rear end of which extends a thumb or finger lug 18. The pivotal point 19 of the members 17 and 1a is arranged a slight distance beyond. the lower edge of the rounded portion 20 of the block 17. In this connection reference is had to the cutting edge of the member 11, as the forward extremity of the structure. it will be readily observed that by lifting the por tion 18 of the member 17, upwardly, the block will roll on the rounded edge 20, consequently permitting the member 17 to rotate on the rod 16, swinging the forward terminal of the member 14: upwardly and out of engagement with the iron 11. The member 9 will then be manipulated to adjust the iron 11 to the proper extension through the slot 6, and by pressing down on the portion 18 of the member 17, the forward terminal of the member 1% will again grippingly enage the member 11 and hold it locked against shifti movement. It is desirable to em )hasize at this point that the locking dog above disclosed exerts a locking pressure on the iron 11 at points adjacent each terminal of the menber, thus providing a most effective method of holding the iron in adjusted position.

Coming now to the description of the teat of this plane, there are provided two members of this character designated as entireties by the numerals 21 and 22. The toat 21 is of the customary knob structure, and is seecured forwardly of the shoe 2 by means of a bolt or other suitable fastening device 23, preferably screw threaded at its lower terminal in a boss 24 formed in the upper face of the shoe 2. The toat 22 is of the usual construction, so far as the main body portion is concerned, but differs from the ordi nary toat in that it is removably attached to the shoe of the plane. The means employed in attaching the member 22 includes a base plate 25, secured to the lower terminal of the body portion of the member 22 by a bolt 26. The member is preferably rectangular in shape and is beveled as at 27 on each edge to permit the plate to be slidably mounted in the wedge-shaped grooves 28 formed in a U-shaped metallic frame 29. The member 29 may be bolted or otherwise secured to the shoe 2 or may be formed integrally therewith circumstances may require. In order to prevent the turning of the body portion of the member 22 on the plate 25, there have been provided a plurality of studs 80 formed integrally with the member 25 and projecting upwardly therefrom in such manner that they may be embedded in the lower terminal of the body of the teat, as clearly illustrated in Fig. 1. As a means for detachably holding the plate 25 in the frame 29, this invention utilizes an arcuate leaf spring 31, the terminals of which are mounted for sliding movement through suitable recesses 32 formed in the free ends of the side members of the frame 29, as disclosed in Fig. 5. By reference to Fig. 4; it will be observed that when the plate 25 is disposed in assembled position within the frame 29, the spring 31 bears against the adjacent edge of the plate and acts to prevent the withdrawal of the plate. lVhen ll: is desired to remove the toat 22 it is only necessary to press down on the spring 31, the free ends of which will recede into the recesses 32, thus permitting the plate 25 to withdraw from the frame 29.

The actual manipulation of the various adjustable parts of this invention being thus disclosed, it now remains to describe the manner in which a set of planes may be disassembled to be packed in a Very small space. In this connection reference is had to Fig. 6. In this view it will be obsewed that there are three planes of different sizes designated by the le ters A, B and C, the letter A indi eating a small smoothing plane, the letter B the jack plane, and the letter C the fore plane. It will be found very practical to manufacture the planes in sets, as disclosed in Fig. 6, making the combined length oi the smoothing plane and jack plane equal to the length of the foreplane. lVhen made in sets of this type, the three planes may be readily placed in a single box, equal in length and depth to the corresponding di mensions of the fore plane, by merely removing the handles from each of the planes.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claim.

What is claimed is The combination with a plane of a detachable toat including a body portion, a rectangular plate, means for securing said rectangular plate to said body portion at the lower terminal thereof, said base plate be ing chamfered on its forward transverse edge and side edges and straight on its rear transverse edge, a substantially U-shaped frame, said frame being provided with grooves on its inner, forward edge and side edges to receive the chamfered edges of said base plate and provided with transverse grooves adjacent its free terminals and an arcuate leaf spring having its terminals slidably mounted in the recesses in the frame, said spring adapted to hold said base plate in assembled position by engagement with the rear strai 'ht transverse edge thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
